We are rebuilding Porsche cariera 911, year 1991, NA 3.6 air cooled motor
(H6), fuel - methanol, ITBs, injectors.
Any info about trigger is highly appreciated.
Primary trigger
- VR or HALL ???
- pattern ?
Secondary trigger
- VR or HALL ???
- pattern ?
On-site measurement is very easy and recommended in any case.
If you find 2 pins that show same resistance (usually between 300..1400 Ohm ; take note of actual reading) in both directions, that is VR sensor. Otherwise HALL.
We like to equip it with Vems engine management:
- 2x WO2 sensors
- 6 x EGT sensors
- I-button
- SD-logger
Basic sensors:
- MAP sensor
- IAT sensor
- TPS
- cylinder head temeperature (instead of coolant temp)
- lower than 150C right ?
- oil temperature
extra analog inputs:
- presure
- oil fan switch
- crank & cam sensors
- fuel pressure
- fuel pump switch
ITB - idle air
Are you feeding controlled idle air
- with 1 PWM solenoid valve via 6 small tubes ?
- measured resistance= ... ???
- or 1 actuator acting on the ITB-shaft (or stop-point) ?
- or 2 actuators ? (if so, this solution requires the most care and attention)
- or 0 actuator, relying only on mechanical stops / screws ?
[local search for Porsche] - Peep himself installed more than 20 Porsches (but maybe not this type), and perhaps someone else knows even better.
The preparation (finding out VR/HALL) is the easier part; do some measurements, searching, and hang around ChatViaIrc
